Ear infections (otitis externa) are among the most common reasons dogs visit veterinarians. Chronic otitis causes significant pain and often reflects underlying allergic disease requiring management.
Otitis externa causes significant pain that is frequently undertreated because dogs habituate to chronic discomfort. The dog that has scratched at its ear for months has often stopped showing obvious distress despite ongoing pain. Chronic infections cause progressive structural changes — wall thickening, canal narrowing, calcification — that eventually create permanent damage requiring surgical intervention. The key to managing recurrent otitis is identifying and treating the underlying cause: in most cases, this is allergic skin disease. Treating only the infection without addressing allergy creates a cycle of recurrence with escalating antibiotic resistance. Regular ear cleaning in predisposed breeds — using appropriate cleaning solutions rather than water — removes debris and excess moisture that promote bacterial and yeast growth. Early veterinary assessment enables treatment before structural changes become irreversible.
